Calculating Power Factor in an A.C. Circuit | Electrical Engineering

The below mentioned article provides a formula for calculating power factor in the A.C. circuit. The power in watt absorbed by a d.c. circuit is known when the supply pressure in volt across the circuit is multiplied by the current in ampere flowing through the circuit. But in an a.c. circuit the product of supply pressure and the circuit current [...]

A.C. Circuit Containing Resistance and Inductance | Current | Electrical Engineering

The current flowing through a d.c. circuit is given by the voltage applied across the circuit divided by the resistance of the circuit. But in an a.c. circuit this simple relationship does not hold good. Alternating currents set up magnetic effects and alternating e.m.fs. set up electrostatic effects, and these effects must be taken into account. With comparatively low voltage [...]
